LED Slot Machine
By Podeanu Marius-Bogdan 1222A
Introduction
LED Slot Machine este un mini joc distractiv in care 3 LED-uri se aprind intr-o culoare la intamplare. Scopul jocului este de a avea toate LED-urile aprinse in aceeasi culoare. In momentul in care castigi, muzica incepe sa cante iar pe ecranul LCD iti apare un mesaj.
Ideea a pornit de la varianta clasica de slot, dar facuta in asa fel incat sa fie cat se poate de fair.

Libraries Used:
The only library needed was the one for the I2C LCD.
Obtained Results
After many tries, I made it so that the game works. Now, when you press the button, the RGB's turn on into a random color.
If all 3 RGB's have the same color, the buzzer will start singing and the LCD will display a different message.
Soon, I will put it to use and make my friends pay in order to play with it.
Conclusion
The project was very interesting. I learned alot of new things, how to use arduino, and how to search things better on the internet.
After this project, I wish to do more arduino projects in the near future.
Journal
I started by doing the project in Tinkercad, so that I can do trial and error there.
After I was done with it in Tinkercad, and I saw that it worked, I ordered my components and I got them.
I started thinking how should I arrange it so that it's not messy and I found the solution.
Without realising it, the project was already done.
